JA Solar to Supply 490 MW Solar Modules for UHV Transmission Project

JA Solar has won the bid for supplying 490 MW of high-efficiency modules for Huanghe Hydropower’s ultra-high voltage (UHV) Transmission Project in China.

JA Solar, a leading manufacturer of high-performance photovoltaic (PV) products, has announced that it won the bid for supplying 490 MW of high-efficiency modules for Huanghe Hydropower’s ultra-high voltage (UHV) Transmission Project in Qinghai Province, China. Huanghe Hydropower is a subsidiary of SPIC (State Power Investment Corporation), one of the biggest power investors in China. 

The project, with a scale of 3.1 GW, is the world’s leading UHV demonstration project. This is also of great significance for the application of new technologies and the exploration of deploying renewable energy projects with UHV.

JA Solar will supply its mono PERC 9BB half-cell bifacial double-glass modules for the project, facilitating the integration of advanced solar products and the UHV power grid. With a mass production output power of 410 W and conversion efficiency of 20.4 percent, this advanced product incorporates some of the leading technologies, including bifacial cell, 9BB, half-cell and double-glass structure.

Jin Baofang, chairman of the Board of Directors of JA Solar, said that the Huanghe Hydropower Development Co., Ltd is a large comprehensive energy company under the State Power Investment Corporation. With a 20-year experience in the construction and development of solar photovoltaic power stations, it has maintained a long-term cooperative relationship with JA Solar.

“We are honored to cooperate with Huanghe Hydropower on the pioneering project, and will continue to work with our cooperative partners to promote the large-scale application of high-efficiency products to enable the industry to reach grid parity globally.”

The 9BB technology decreases resistance loss; half-cell technology enables better performance in shaded conditions, and the double glass structure allows better adaptability to different environments. Additionally, gallium doping technology is applied to the silicon wafers for effectively mitigating light induced degradation (LID). All of these technologies ensure that the module optimises power-generating performance. With its strong reliability and environmental adaptability, JA Solar’s advanced module has passed the testing of TUV Nord and Intertek and is ideal for reducing the balance of system (BOS) cost and LCOE.
